Overview

Tacker provides some examples, or templates, of local.conf used for Devstack. You can find them in ${TACKER_ROOT}/devstack directory in the tacker repository.

Devstack supports installation from different code branch by specifying branch name in your local.conf as described in below. If you install the latest version, use master branch. On the other hand, if you install specific release, suppose ussuri in this case, branch name must be stable/ussuri.

For installation, stack.sh script in Devstack should be run as a non-root user with sudo enabled. Add a separate user stack and granting relevant privileges is a good way to install via Devstack¹.

Install

Devstack expects to be provided local.conf before running install script. The first step of installing tacker is to clone Devstack and prepare your local.conf.

Download DevStack

Get Devstack via git, with specific branch optionally if you prefer, and go down to the directory.
```
$ git clone https://opendev.org/openstack-dev/devstack -b <branch-name>
$ cd devstack
```
Enable tacker related Devstack plugins in local.conf file

local.conf needs to be created by manual, or copied from Tacker repo² renamed as local.conf. We have two choices for configuration basically. First one is the all-in-one mode that installs full Devstack environment including Tacker in one PC or Laptop. Second, it is standalone mode which only will install only Tacker environment with some mandatory OpenStack services. Nova, Neutron or other essential components are not included in this mode.
1. All-in-one mode
  
  There are two examples for all-in-one mode, targetting OpenStack or Kubernetes as VIM.
  
  local.conf for all-in-one mode with OpenStack³ is shown as below.
  
  ../../../devstack/local.conf.example
  
  The difference between all-in-one mode with Kubernetes⁴ is to deploy kuryr-kubernetes and octavia.
  
  ../../../devstack/local.conf.kubernetes
  
  Note
  
  The above local.conf.kubernetes does not work on CentOS8. Because docker-ce is not supported on CentOS8.
2. Standalone mode
  
  The local.conf file of standalone mode from⁵ is shown as below.
  
  ../../../devstack/local.conf.standalone
Installation

After saving the local.conf, we can run stack.sh in the terminal to start setting up.
```
$ ./stack.sh
```
